The coax is shorted at the end, and Gnd is 45
degrees away from the short.

What is the impedance of the voltage delivered from Vs before the wave encounters the resistor Rs?

Assume that Rs is 100% of the source impedance.

What reflection characteristics should we assume for the voltage source Vs?

Assuming that Rs is 100% of the source impedance
should answer that question.

Is this a standard ideal voltage source which provides energy
to the circuit when the product of its voltage and current is
positive and removes energy from the circuit when the product
of its voltage and current is negative?

Or have you assigned it some other non-standard definition?
